From the graph you can see that it is a (4 x 3) rectangle with two (right) triangles attached  (base 4   h  2)

You have been shown how to do several of these similar graphs.....try to figure out an answer and get back to me if you have questions......

I don't get it! Do I have to do the triangles first with pythagorean theorem?

I got 11.6 for the perimeter

Let's see...

Two short sides of the rectangle = 2 x 3 units = 6

and FOUR triangle legs (they are all of equal length)....you can use pythag  theorom or distance formula for points

using pyhtag      x^2+x^2 = 4^2

2x^2 =4^2

x^2 = 2      x = sqrt 2

FOUR of them = 4 sqrt 2 = 5.66 units               5.66 + 6 =11.66 units

It appears YOU GOT IT!!!!

Now work on the area.....add the rectangle area + TWO triangle areas = ?

My problem is I don't know how to get the area... I literally got 5.8 lol

AREA of rectangle  = H x W   = 3 x 4 = 12 sq units

Area of EACH triangle = 1/2 b * h      b = 4   h= 2      1/2 bh = 1/2 4 *2 = 4

there are TWO triangles    total triangle area = 8

12 + 8 = 20 sq units total area

Thank you so much! I feel like the area was easier and yet I couldn't figure it out lol but i get it now
